Embodiment Construction

[0010] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0011] figure 1 Shown is a flow chart of the two-dimensional code color coding method provided according to a preferred embodiment of the present invention. Such as figure 1 As shown, the two-dimensional code color coding method provided by the preferred embodiment of the present invention includes steps 101-102.

[0012] Step 101: the two-dimensional code generator converts the character into a byte array corresponding to the utf-8 encoding of the character, and determines the color value corresponding to the character according to the first preset strategy, and the two-dimensional code generator converts the color value Draw in the data area of ​​the QR code, form a QR code image and send it to ...

Abstract

The invention provides a method and a system for coding two-dimensional code colors. The method includes the steps: converting characters into a byte array corresponding to utf-8 codes of the characters by a two-dimensional code generator; determining color values corresponding to the characters according to a first preset policy; and drawing the color values in a two-dimensional code data area, forming a two-dimensional code picture and then transmitting the two-dimensional code picture to a calculator by the two-dimensional code generator. A decoder reads and analyzes the two-dimensional code picture to be processed, obtains the color value of the two-dimensional code picture to be processed and informs the calculator, wherein the two-dimensional code picture is stored in the calculator. The calculator inquires a color interval table, obtains the corresponding characters and transmits the corresponding characters to the decoder. The calculator is used for determining the color interval table according to a second preset policy according to the color values corresponding to the characters.

Description

technical field [0001] The invention belongs to the field of instant communication, and in particular relates to a two-dimensional code color coding method and system. Background technique [0002] With the rapid development of society, science and technology are more and more applied to people's life. At present, in the circulation process of various commodities, in order to increase the information capacity, many commodities will be marked with two-dimensional codes. Compared with the previous barcodes, two-dimensional codes can accommodate more text information. At present, the two-dimensional code is mainly a combination of black and white blocks, and the character capacity that can be stored is small, which greatly reduces the practical application value of the two-dimensional code. Contents of the invention [0003] The present invention provides a two-dimensional code color coding method and system to solve the above problems. [0004] The invention provides a two...
